Abstract (en)
Drawing unit and method for drawing at least one long metal product (P), configured to make the at least one long metal product (P) advance along a nominal axis of feed (A) and provided with at least a first motorized roll (13) and with at least two second rolls (14) operating at the periphery of the first roll (13) and defining, with the latter, respective passage gaps (15). The at least two second rolls (14) are located one on one side and the other on the other side of the axis (N) orthogonal to the nominal axis of feed (A) that passes through the center of rotation of the first roll (13). The second rolls (14) are associated to movement members (21) to move the second rolls (14) in a parallel form with respect to each other and in a direction substantially orthogonal to said nominal axis of feed (A) in order to adjust the passage gaps (15). The passage gaps (15) have, during use, along the straight line (R) that joins the center of the first roll (13) with the center of the respective second roll (14), an amplitude (G) that is bigger in size than the nominal diameter (D) of the metal product (P).
